Worked a treat, thanks. And if anyone is stuck on how to import that OPML file back into iTunes (because there is no corresponding right-click option to Import Podcasts), simply drag the OPML file into the Podcasts window and away you go. The only pain is that iTunes will assume that you have not downloaded the latest versions of any of your subscriptions, and will start to do so.
